* Launch  : February 2009

* Released: Tuesday 12th May, 2009 - 00:00
* Debug: jquery.qtip.debug.js
* A few minor fixes added by Dustin Moore, dustmoo@gmail.com---
* ---Added Craigs opacity fix for to the afterShow function to prevent the tip opacity rendering
* ---Raised the z-index to a higher maximum to prevent z-index conflicts
* ---Added functionality so that unfocus can be used with other hide actions, i.e. unfocus and mouseout
* ---Various IE fixes as well as jQuery 1.4.1 compatability updates.
